The specific embodiment
In order to describe structure of the present utility model, characteristics and effect in detail, the existing act under following preferred embodiment and the conjunction with figs. explanation.
At first, as Fig. 1～shown in Figure 4, the punch press of the improvement oil pipeline configuration that the utility model one preferred embodiment is provided, it is connected with an oil pressure source (not shown), and this punch press includes:
One lower support 10, has a pedestal 11, be positioned at the bottom side of this punch press, two through holes 111 are offered respectively through pedestal 11, one chassis 13 is arranged in pedestal 11 top sides, four support column holes 131 (part is not shown in the figures) offer through the chassis 13 respectively, and wherein two through holes 111 of pedestal 11 are the support column hole 131 on corresponding connected component chassis 13.
One support column group 20 includes one first cylinder 21, one second cylinder 22, one the 3rd cylinder 23, one the 4th cylinder 24, supports and then increase the steadiness of punch press to constitute the four directions.Each cylinder is arranged in the four support column holes 131 on chassis 13 respectively and puts a sleeve 25 respectively, wherein first cylinder 21 and second cylinder 22 are cylinder, one first passage 211 and a second channel 221 are circular hole and are opened in first cylinder 21 and second cylinder 22 with its cylinder concentric respectively, and first cylinder 21 and second cylinder 22 are respectively established a screw 213,223 at the both ends open place.
One upper frame 30, has a plate body 31, four support column holes 33 are run through and are formed at plate body 31, be arranged in each cylinder 21,22,23,24 of support column group 20 for upper frame 30, the center that is formed at plate body 31 is run through in one oil hydraulic cylinder hole 35, one groove 351 is formed at oil hydraulic cylinder hole 35 sides, and four guide pillar holes 37 are run through and are formed at plate body 31.
One oil hydraulic cylinder 40, have a cylinder body 41, be installed in the oil hydraulic cylinder hole 35 of upper frame 30, but a bearing axle 43 is arranged in cylinder body 41 and axial stretching displacement, one first oilhole 45 is located at cylinder body 41 end faces, and one second oilhole 47 is located at the groove 351 that section side, 41 end of cylinder body can be placed in unit 30.
One oil pipe group 50 has one first oil pipe 51, and its two ends connect respectively establishes the screw 213 that a pipe joint 511, two pipe joints 511 connect first cylinder 21 of first oilhole 45 of oil hydraulic cylinder 40 and support column group 20 respectively.One second oil pipe 52, its two ends connect respectively establishes the screw 223 that a pipe joint 521, two pipe joints 521 connect second cylinder 22 of second oilhole 47 of oil hydraulic cylinder 40 and support column group 20 respectively.
Four guide pillar groups 60 respectively include a guide pillar 61, and are fixed in the guide pillar hole 37 of upper frame 30 by two guide pin bushings 62.
One die holder 70 of locking, has a pedestal 71, its top side is arranged in the bearing axle 43 of oil hydraulic cylinder 40 and four guide pillars, 61 bottoms of guide pillar group 60, the die holder 70 of locking is driven and axial displacement by the bearing axle 43 of oil hydraulic cylinder 40, and provide the correcting track by guide pillar group 60, and then the die holder 70 of locking does not have skew when axial displacement.
Wherein, screw 213 beginnings by first cylinder 21 of support column group 20 connect first oilhole 45 of first oil pipe 51 of oil pipe groups 50 to oil hydraulic cylinder 40 through first passage 211, form first oil pipeline of punch press.Similarly, screw 223 beginnings by second cylinder 22 of support column group 20 connect second oilhole 47 of second oil pipe 52 of oil pipe groups 50 to oil hydraulic cylinder 40 through second channel 221, form second oil pipeline of punch press.
Via said structure, the punch press of the improvement oil pipeline configuration that present embodiment provided, its operation program operation is as follows:
At first, the oil pipe (not shown) of oil pressure source is passed lower support 10 pedestal 11 through hole 111 and be engaged in the screw 213 of first cylinder 21 of support column group 20, so first oil pipeline is connected in oil pressure source.Similarly, another oil pipe (not shown) of oil pressure source pass lower support 10 pedestal 11 through hole 111 and be engaged in the screw 223 of second cylinder 22 of support column group 20, so second oil pipeline is connected in oil pressure source.
Then, when oil pressure source through first oil pipeline and oil hydraulic cylinder 40 is delivered in oil-feed, and oil hydraulic cylinder 40 also by the second oil pipeline oil extraction to oil pressure source, and then the bearing axle 43 of oil hydraulic cylinder 40 is stretched out drive the die holder 70 downward punching presses of locking.
On the contrary, when oil pressure source through second oil pipeline and oil hydraulic cylinder 40 is delivered in oil-feed, and oil hydraulic cylinder 40 via the first oil pipeline oil extraction to oil pressure source, and then make bearing axle 43 withdrawals of oil hydraulic cylinder 40 and drive the upwards retraction of die holder 70 of locking.Therefore, punch press makes die holder 70 knee-actions of locking by the oil extraction of advancing of first oil pipeline and second oil pipeline.Wherein be controlled to be known technology, do not describe in detail for this reason at this about the oil-feed of oil pressure source and the commutation of oil extraction.
Therefore, present embodiment can not cause oil circuit to damage because the action route of the die holder 70 of locking is got involved on the oil distributing pipe road, and not crossover and the identification easily mutually of the oil circuit of punch press, has convenience in the maintenance of carrying out oil circuit or when overhauling.
In addition, as shown in Figure 5, the punch press that the improvement oil pipeline that is provided for another preferred embodiment of the utility model disposes, the difference of itself and the foregoing description is: the 3rd cylinder of support column group is provided with a third channel, and the oil pipe group has additional one the 3rd oil pipe 53, and then forms the 3rd oil pipeline between oil hydraulic cylinder 40A and oil pressure source, wherein, the structure of the 3rd oil pipeline is formed identical with aforementioned oil pipeline, does not narrate for this reason at this.Thus, when oil pressure source during to the first oil pipeline oil-feed and to the second oil pipeline oil extraction, the 3rd oil pipeline is a closed state, and the bearing axle of oil hydraulic cylinder 40A is then to bottom offset.When oil pressure source during to the first oil pipeline oil extraction and to the second oil pipeline oil-feed, the 3rd oil pipeline is an open state and can discharge oil, the bearing axle of oil hydraulic cylinder 40A then bounces back, at this moment, help the action of oil extraction via the 3rd oil pipeline, can improve the speed of oil pressure source oil extraction, make the bearing axle involution rapidly of oil hydraulic cylinder 40A, and then make punch press have the more action of high speed.
What this must be illustrated be: the punch press of improvement oil pipeline configuration provided by the utility model, its oil pipeline is to improve known shortcoming via first cylinder of support column group and second cylinder, wherein, the support column group of punch press can adopt different types such as square cylinder or steel plate, have the upper frame of support punch press and the function of lower support, and the support column group can supply the oil pipeline setting of punch press, and then reaches requirement of the present utility model.
By the explanation to above embodiment, it is as follows to conclude characteristics of the present utility model:
1, the utility model can make the action route of punch press separate with oil circuit, can not get involved mutually or crossover, can guarantee the stability of oil circuit running.
2, the utility model can be simplified the configuration of oil circuit and make the oil circuit easy identification, has the convenience in maintenance or the maintenance.
3, it is interlaced that the utility model can be avoided oil pipe, makes punch press integral body comparatively attractive in appearance.
